4. The data set BWGHT.DTA contains data on births to women in the United States. Two variables of interest are the dependent variable, infant birth weight in ounces (bwght), and an explanatory variable, average number of cigarettes the mother smoked per day during pregnancy (cigs). The following simple regression was estimated using data on n=1,388 births: bwght=119.77 - .514 cigs (i) What is the predicted birth weight when cigs = 0? What about when cigs=20 (one pack per day)? Comment on the difference. (ii) Does this simple regression necessarily capture a causal relationship between the child's birth weight and the mother's smoking habits? Explain. (iii) To predict a birth weight of 125 ounces, what would cigs have to be? Comment. (iv) The proportion of women in the sample who do not smoke while pregnant is about .85. Does this help reconcile your finding from part (iii)?

Given the demand equation Q following table (using Excel): = 1,500 200P, calculate all the numbers necessary to fill in the Elasticity P Q Point Arc Total Revenue Revenue Marginal $7.00 6.50 6.00 5.50 5.00 4.50 4.00 3.50 3.00 2.50

Suppose a firm has the following demand equation: where Q = quantity demanded P = product price (in dollars) Q=1,000 3,000P + 10A A = advertising expenditure (in dollars) Assume for the following questions that P =3$ and A = $2,000. 1. Suppose the firm dropped the price to $2.50. Would this be beneficial? Explain. Illustrate your answer with the use of a demand schedule and demand curve. 2. Suppose the firm raised the price to $4.00 while increasing its advertising expenditure by $100. Would this be beneficial? Explain. Illustrate your answer with the use of a demand schedule and a demand curve. (Hint: First construct the schedule and the curve assuming A = $2,000. Then construct the new schedule and curve assuming A = $2,100.)

ABC Sports, a store that sells various types of sports clothing and other sports items, is planning to introduce a new design of Arizona Diamondbacks' baseball caps. A consultant has estimated the demand curve to be where Q is cap sales and P is price. Q=2,000 100P 1. How many caps could ABC sell at $6 each? 2. How much would the price have to be to sell 1,800 caps? 3. Suppose ABC were to use the caps as a promotion. How many caps could ABC give away free? 4. At what price would no caps be sold? 5. Calculate the point price elasticity of demand at a price of $6.

Use this case which you either know about already or have identified through research and address the following questions in essay format: i. Outline and discuss what “triggered” the regulatory body to intervene?                                                                       ii. How effective do you think the response was to such a crisis? iii. Outline and discuss two ways that could be used to strengthen the current regulatory environment?

Home can produce a maximum of 400 apples or a maximum of 600 bananas.Foreign can produce a maximum of 160 apples or a maximum of 800 bananas.(a) Graph and label Homes PPF. Label each axis and the slope. Use numbers.1(b) In the absence of trade, what is Homes autarky price of apples in terms of bananas?(c) Graph and label Foreigns production possibility frontier. Use numbers and label the slope.(d) Graph the world relative supply curve. Use numbers.23. (8 pts - RM) Now suppose world relative demand for apples takes the following form:Demand for apples/demand for bananas - price of bananas/price of apples. That is, RDA = Pbananas Papples(a) Graph the relative demand and relative supply curves on the world market diagram. Use numbers(b) What is the equilibrium (world) relative price of apples? (c) Show that both Home and Foreign gain from Trade and describe the pattern of trade.

A village has six residents, each of whom has accumulated savings of $100. Each villager can use this money either to buy a government bond that pays 18 percent interest per year or to buy a year-old llama, send it onto the commons to graze, and sell it after 1 year. The price the villager gets for the 2-year-old llama depends on the quality of the fleece It grows while grazing on the commons. That in turn depends on the animal's access to grazing, which depends on the number of llamas sent to the commons, as shown in the following table: Number of 11amas on the commons Price per 2- year-old 11ama ($) 1 125 2 119 3 116 4 113 5 6 111 109 The villagers make their investment decisions one after another, and their decisions are public. a. If each villager decides Individually how to Invest, how many llamas will be sent onto the commons, and what will be the resulting village Income? Number of llamas: [ 20 Instructions: Enter your response as a whole number. Village Income: $ 110 b. What is…

5. Discrimination in the labor market The following table exhibits the name, gender, height, and minimum wage 10 people are willing to accept to work as travel nurses at a regional hospital. Name Gender Height Minimum Wage (Inches) (Dollars per week) Cho F 65 $297 Frances F 64 $316 Latasha F 68 $336 Dmitri M 70 $355 Jake M 71 $374 Rosa F 65 $393 Nick M 72 $420 Brian M 71 $439 Tim M 66 $451 Alyssa F 68 $478 The lowest weekly wage that the hospital can spend in order to hire five travel nurses is ________. Suppose the hiring director of the hospital prefers taller candidates because they think it will increase revenue, and so they impose a requirement that all newly hired travel nurses must have a height of at least 68 inches. With this mandate in place, the weekly wage rate the hospital now must pay in order to hire five travel nurses increases by ________.
